pH

Question 1

Autoionization of water

Answer 1

*when atoms/molecules spontaneously transition from an electrically neutral state to a lower-energy ionized state

H2O(l) <=> H+(aq) + OH-(aq)

Question 2

Hydrogen/Hydronium

Answer 2

H+ is incorporated by water molecules and becomes H3O+

Question 3

pH formula

Answer 3

-log[H+]

Question 4

Acid

Answer 4

increases pH by donating H+ through dissociation.

stronger acids more readily dissociate

Question 5

Base

Answer 5

scoops up H+ to raise pH

Question 6

Buffers

Answer 6

solutions that resist change in pH

made up of conjugate acid-base pair
(eg: carbonic acid and bicarbonate ion)
